Utaraptor, the Latin name for the genus Utahraptor, is a genus of predatory dinosaurs of the smallest sizes, not the largest in the dromaeosaurid family. Utahraptors inhabited the Earth during the Early Cretaceous about 130.0-125.0 million years ago in North America.
Fossil bones were found in Utah, (USA), whence came the name of the genus, which is translated from Latin as "kidnapper from Utah" or "thief from Utah."
The utaraptors were predatory animals and had a body length of about 7 meters. These predatory reptiles hunted in small groups and, apparently, had a developed intellect, which is compared with the intelligence of some birds.
In this regard, according to experts, Utah raptors could cope with hunting quite large dinosaurs.Utahraptor (Latin Utahraptor)
As mentioned above, Utahraptor was first discovered during excavations in Utah, Grand County (Cedar Mountain Formation), in 1991 by paleontologists James Kirkland, Rob Gaston and Don Burg. The found parts of the skeleton were sent to the Museum of Prehistoric Life at the College of Geography of Utah, where they were mounted and represent the only skeleton of Utaraptor at the moment.Utahraptor reached 7 meters in length.
The scientific description of Utahraptor was given by the famous American paleontologists John Ostrom and Chris Mays in 1993, who approved the official name of the genus "Utahraptor".The skeleton of Utahraptor.
Earlier, dromaeosaurids were considered small animals, reaching a length of not more than two meters. However, the opinion of dromaeosaurids changed with the discovery of Utaraptor, which reached 7 meters in length. Close relatives of Utahraptor from the dromaeosaurids family were Dromaeosaurus, who lived in the Upper Cretaceous period in North America, and Achillobator giganticus, who lived in Mongolia during the same period in Earth's history.Claws of Utaraptor.
Like all predatory relatives, Utaraptor had a large claw bent like a sickle on each hind limb. This formidable weapon was about 24 cm long.Attack of the Utaraptors on a herbivore dinosaur.
Famous paleontologist Robert Becker is a supporter of the theory that dinosaurs were warm-blooded animals and were relatives of birds. He wrote the book Red-skinned Predator, in which, based on scientific research, but using artistic techniques, describes a year in the life of a Utahraptor female: her adventures, trials, experiences, and family relationships. The “reasoning” of dinosaurs is reflected in the book in the form of the way of thinking of animals. Although the Utaraptors in this work do not possess plumage, however, they display some qualities of birds, for example, in the flock hierarchy and in body language.
